Abstract

Буровое долото, конструкция которого предусматривает вращающуюся шарошку для образования скважины в земле. По меньшей мере один венец режущих элементов оптимизирован для создания эффекта блокированного скола горной породы и устранения образования гребней на забое, причем в этом венце выбранные шаги имеют математически определенные пары, а абсолютная величина разницы между выбранным шагом и его парой превышает 10% разницы между максимальным и минимальным шагами для этого венца. Кроме того, режущие элементы расположены вдоль предварительно выбранных образующих со смещением от упомянутых образующих, которое составляет менее чем половину максимального шага венцов, в которых размещен упомянутый режущий элемент. Изобретение устраняет образование гребней на забое и ослабляет вредные продольные вибрации резонансной частоты при уменьшении количества режущих элементов, включая твердосплавные пластины, по сравнению с известными шарошечными буровыми долотами, используемыми для бурения нефтяных, газовых и взрывных скважин, с одновременным повышением производительности бурения, стойкости инструмента и скорости проходки.A drill bit, the design of which provides for a rotating cutter to form a hole in the ground. At least one ring of cutting elements is optimized to create the effect of blocked rock cleavage and eliminate the formation of ridges at the bottomhole, and in this crown, the selected steps have mathematically determined pairs, and the absolute value of the difference between the selected step and its pair exceeds 10% of the difference between the maximum and minimum steps for this crown. In addition, the cutting elements are located along the preselected generatrices with an offset from the said generatrices, which is less than half the maximum pitch of the rims in which the said cutting element is located. The invention eliminates the formation of ridges at the bottom and attenuates the harmful longitudinal vibrations of the resonant frequency with a decrease in the number of cutting elements, including carbide plates, in comparison with the known roller cone drill bits used for drilling oil, gas and blast holes, while increasing drilling productivity, tool life and penetration rate.
